This premium Lightweight Expanded Clay Aggregate (LECA) is a high-performance substrate manufactured by firing premium natural clay in a rotary kiln at extreme temperatures. This process causes the clay to expand into highly porous, lightweight spheres with a varying diameter of 8–16mm. Featuring a rigid, sterile outer shell and a micro-porous internal core, Hydro Clay provides the ultimate structural foundation for rapid root zone aeration and instant drainage.\u003c\/p\u003e\n\u003cp\u003ePurchasing this product in a full commercial pallet of 44 bags provides the most cost-effective bulk medium solution for large facilities. It is ideal for scaling up extensive recirculating commercial greenhouse systems or packing out vast industrial crop benches. Completely inert, chemically neutral, and structurally stable, Hydro Clay ensures it will not break down, compact, or alter your water reservoir’s nutrient balance over long, high-frequency crop cycles.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cb\u003eBest For:\u003c\/b\u003e Large-scale Deep Water Culture (DWC) arrays, automated flood-and-drain (ebb and flow) tables, commercial top-feed drip systems, commercial aquaponics, industrial pot-lining drainage layers, and wholesale potting mix aeration amendments.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCommercial Bulk Logistics:\u003c\/b\u003e Supplied as a full freight-wrapped pallet of 44 heavy-duty 50L bags, delivering a massive 2,200 Litres of premium media to your loading dock for major commercial build-outs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimised 8–16mm Mixed Sizing:\u003c\/b\u003e The varying diameter of the clay balls ensures they interlock cleanly within large net pots, crop baskets, and drainage channels, providing superior structural support for heavy plants while leaving massive macro-porous air gaps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Root Zone Aeration:\u003c\/b\u003e By maintaining an open, uncompactable matrix, Hydro Clay ensures that fresh oxygen is constantly available to the rhizosphere, driving explosive lateral root development and protecting against root rot (Pythium).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e100% Inert \u0026amp; pH Neutral:\u003c\/b\u003e Unlike inferior clay resources that can cause aggressive pH spikes, Professor's Hydro Clay is pre-stabilised and completely neutral, giving you absolute control over your precision liquid nutrient feeding regime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInfinite Reusability \u0026amp; Asset Value:\u003c\/b\u003e Highly durable and physically robust, these clay pebbles do not degrade or dissolve.
